Ultimate Pit Limit Determination Methods

In this study, the importance of determining the ultimate pit limits and block model concept used for this purpose, were examined. Then Dynamic Programming, Graph Theory, Maximum Flow Algorithm and Moving Cone Algorithm which are commonly used to find the pit limits were examined in detail. A two-dimensional block model example is optimized by using above 4 methods, and the results obtained are compared. According to the results obtained, advantages and disadvantages of the methods are outlined.
